Definitions

  • the present invention relates to an electrical multiple stage switch assembly comprising an assembly casing, a first component carrier, and at least one switch, each multiple stage switch comprising a first convex disc contact, a second convex disc contact, and an actuator means.
  • the first and second disc contact are positioned with their centres substantially aligned and respective actuator means is positioned in the assembly casing and adapted to compress the first and second disc contact.
  • the first and second disc contact are adapted to flex into an electrical connection when the actuator means is pressed and to flex back into a non-electrical connection when the actuator means is released.
  • the first disc contact is positioned on the first component carrier in a fixed electrically conductible manner.
  • the inventive multiple stage switch assembly can be used for remote control assemblies in both wired and wireless control applications for the control of machinery in different industrial applications, such as for the control of cranes.
  • Two stage switch assemblies are previously known where the assembly carries a number of two stage switches.
  • switches be made more compact, requiring a minimum of space in an apparatus and yet be simple and reliable. It is another requirement that the switches be sealed in order to be applicable for installation on boards where fluid techniques such wave soldering are used. If the switch is not sealed, internal corrosion of the contacts due to contaminants would occur in the switch.
  • the operator expects to feel a switching action such as when going from one switch function to another.
  • switches having internal contacts implemented with convex discs or domes positioned one above the other in a spaced relationship having their respective centers substantially in alignment.
  • a flex or snap-action occurs when an operator pushes down on a push button which applies a force to the center of the domes.
  • the operator can sense the snapping movement of the center portion of a first dome and then the snapping movement of the center portion of a second dome positioned under the first dome. This sensation is commonly known as "tactile feedback".
  • the flexing of the dome causes an electrical connection to occur first between the upper dome and the lower done, and then with further pressure on the push button, the lower dome makes electrical connection with a terminal in the base of the switch assembly.
  • a switch has a normally open position and two other positions for making electrical connection.
  • Such a switch assembly has to be assembled with low cost parts and low cost efficient means in order to be viable in the market place. Securing the lower dome may provide wider applicability of the switch.
  • Publication US 4 659 881 discloses an electrical switch assembly with a pair of conducting resilient domes which snap inwardly to produce corresponding switching functions when downward pressure is applied at their respective centers and snap outwardly to produce opposite switching functions when the applied pressure is removed.
  • the pair of domes are supported one within the other in spaced relation with their respective centers substantially in alignment.
  • Pressure applying means such as a push button, is mounted for movement in line with the aligned centers of the outer and inner domes to a first predetermined position to snap the outer dome inwardly and to a second predetermined position to snap the inner dome inwardly.
  • the successive snapping actions of the two domes to produce corresponding switching functions provide respective stages of tactile feedback through the push button to the operator.
  • Publication EP 0 920 040 B1 discloses push button sealed, dual action, tactile feedback, electrical switch assembly of the type wherein an operator senses tactile feedback from switch contacts flexing when pressure is applied to the switch assembly. It comprises a first convex disc contact having a plurality of tabs extending therefrom, a second convex disc contact having a plurality of tabs extending therefrom, the first convex disc contact positioned above the second convex disc in a spaced apart relationship having their centres substantially aligned.
  • Actuator means positioned above the first convex disc contact and adjacent thereto for moving a first predetermined distance causing the first convex disc contact to flex and be in electrical contact with the second convex disc contact and moving a second predetermined distance causing the second convex disc contact to flex and be in electrical contact with a base contact.
  • Respective stages of the tactile feedback are provided by the flexing of the first convex disc contact and the second convex disc contact in response to movement of the applied pressure to the first predetermined distance and the second predetermined distance. The first convex disc contact and the second convex disc contact return to their original non-flex state when the applied pressure is removed.
  • the base means comprises a first plurality of multi-sided bins for positioning the tabs of the first convex disc contact in a first plane
  • the base means comprises a second plurality of multi-sided bins for positioning the tabs of the second convex disc contact, the second plurality of multi-sided bins being positioned approximately forty-five degrees from the first plurality of the multi-sided bins and in a second plane above the first plane.
  • each multiple stage switch comprise at least one second convex disc contact, meaning that it is possible to stack several disc contacts in one switch and thus achieving a true multiple stage switch with one stage for each disc contact.
  • the switch assembly comprises one second component carrier for the second disc contact, to which each second disc contact is connected, and at least one controlling member.
  • each second component carrier is electrically connected to the first component carrier thereby connecting each second disc contact to the first component carrier.
  • each second disc contact is connected respective second component carrier in a flexible, yet electrically conductible, manner.
  • Each controlling member comprises a controlling part for each switch, and a controlling member is positioned between the component carriers in a way so that each disc contact is facing a controlling part.
  • the controlling part is connected to the controlling member in a flexible manner in order to enable the controlling part to follow the movement of respective disc contact as the contacts are pressed by the actuator means and as they flex back when released.
  • the controlling member is made out of a flexible material in order to provide the flexible connection of the controlling part, which has to be a material that can endure the required number of actuations with a maintained mechanical flexibility.
  • An example of a flexible and endurable material that can be used is Polyoxymethylene (POM).
  • the controlling part comprises a spacing member adapted to limit the smallest possible distance between adjacent component carriers, thus limiting the highest possible compression from the actuator means.
  • controlling part comprises a counter protrusion facing the disc contact, where the counter protrusion is recessed at the centre of the disc for concentrating the applied pressure on the convex disc contact.
  • the controlling part comprises a first counter protrusion facing one disc contact and a second counter protrusion facing the other disc contact, and that respective counter protrusion is recessed at the centre of the disc for concentrating the applied pressure on the respective convex disc contact.
  • each second disc contact is connected to respective second component carrier by means of a connector that will allow the required movement of the second disc contact, such as by means of flexible circuit carrier. It is important that the flexible circuit carrier allows required movement of the second disc contact and can endure the required number of actuations with a maintained electrical conductivity, mechanical flexibility and mechanical strength.
  • a material for a flexible circuit carrier that is PI SF305C 1025.
  • the whole second component carrier can be manufactured by a flexible circuit carrier, however, it is also possible that only the connector is made out of the flexible material, in which case the rest of the second component carrier can be made out of a more rigid material, such as FR4 IT180A.
  • An alternative way of providing a flexible and yet electrically conductible connection of the second disc contact to its second component carrier is to use an electrically conducting wire.
  • each surface area and recess of respective counter protrusion is adapted to the size and curvature of the convex disc contact that it is facing.
  • each convex disc contact in a multiple stage switch is adapted to flex into a an electrical connection at a force from the actuator means that is different from the force required to flex any other convex disc contact in the same multiple stage switch into a an electrical connection, thereby enabling a clear and distinct multiple step tactile feedback to the operator.
  • first and respective second component carriers are described as separate component carriers, however, it is also possible that the first and each second component carrier are made out of one flexible component carrier that is folded to form the first and each second component carrier positioned on top of each other.
  • the first and each second component carrier are sealed where possible, that the assembly casing and actuator means are weatherproof, that the assembly casing and actuator means are adapted to requirements for mechanical strength, and/or that the switch assembly is a sealed, weatherproof and EMC certified unit.
  • the advantages that foremost may be associated with a multiple state switch assembly according to the present invention are that the invention provides a compact switch assembly with low building height and a high density of switches on the switch assembly.
  • the compact design is valuable even in a switch assembly with only one multiple stage switch providing space for other components or enabling a very small switch assembly.
  • One or several controlling members are adapted to the design of the switch assembly and are then inexpensive and easily pre-produced. Every convex disc contact is mounted to its respective component carrier and the component carriers and required controlling members are easily mounted into a switch assembly. Required disc contacts are mounted to their respective component carriers together with other components belonging to the switch assembly, such pre-produced component carriers together with the pre-produced controlling member(s) provides an inexpensive, time effective and relatively simple production of the switch assembly.
